Table Torque

Three legs placed equal distances apart on the edge support a 36-kg round table. What minimum mass, placed in the table's edge, will cause the table to turn over? Hint: Place the mass equally inbetween two legs.

Im studying for my exam and going through problems I got wrong, trying to fix them, heres what I did.

When the table is just about to tip, the torque exerted by the applied force will equal the torque exerted by the weight of the table. The axis of rotation is the line joining two legs: Find the torques that the forces make about that line. Hint: find the distance the forces are to that line in terms of the radius R.
